Merge tag 'asoc-v6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v6.6
The rest of the updates for v6.6, some of the highlights include:
- A big API cleanup from Morimoto-san, rationalising the places we put
functions.
- Lots of work on the SOF framework, AMD and Intel drivers, including a
lot of cleanup and new device support.
- Standardisation of the presentation of jacks from drivers.
- Provision of some generic sound card DT properties.
- Conversion oof more drivers to the maple tree register cache.
- New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43,
various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive
JH7110.
